Suppose that a conservative political alliance succeeds in 2020 to change the current floating exchange rate regime in the U.S. into a fixed exchange rate regime. Assume that the fixed exchange rate is announced to be equal to the current market equilibrium rate. However, on March 1 of the same year, a speculative attack on the dollar takes place. Demonstrate, step by step, why a speculative attack on the dollar takes place and explain with each step how and why each market participant makes his move. Add as many steps as you think are necessary to explain your answer.
Step 1: Time: January 1, 2000, 1$ = 100¥ (Dollar vis-a-vis Yen)
Step 2: Time: March 1, 2000
